Metacestodes of the family Dilepididae (Cestoda: Cyclophyllidea) parasitising fishes in Mexico

A survey of metacestodes of dilepidid tapeworms (Cyclophyllidea) occurring in fish from Mexico is presented. They belong to the following species (those first reported from Mexico marked with an asterisk): Cyclustera capito (Rudolphi, 1819); ^* Cyclustera cf. ralli (Underwood & Dronen, 1986); Dendrouterina pilherodiae Mahon, 1956; ^* Glossocercus auritus (Rudolphi, 1819); ^* G. caribaensis (Rysavy & Macko, 1973); ^* Paradilepis caballeroi Rysavy & Macko, 1973; ^* Paradilepis cf. urceus (Wedl, 1855); ^* Paradilepis sp.; Parvitaenia cochlearii Coil, 1955; ^* Parvitaenia macropeos (Wedl, 1855); ^* Valipora campylancristrota (Wedl, 1855); ^* V. mutabilis Linton, 1927; and ^* V. minuta (Coil, 1950). Metacestodes of Dendrouterina papillifera (Fuhrmann, 1908), previously reported from the gall-bladder of the pimelodid catfish Rhamdia guatemalensis from Mexico by Scholz et al. (1996), belong actually to V. minuta. Data on the morphology of metacestodes, their fish hosts and rate of infection, site and distribution in Mexico are provided.     

Taxonomic revision and phylogenetic analysis of the cestode genus <Emphasis Type="Italic">Paraprogynotaenia</Emphasis> Rysavy, 1966 (Cyclophyllidea: Progynotaeniidae)

The type-series of Paraprogynotaenia jimenezi Rysavy, 1966 [type-species of Paraprogynotaenia Rysavy, 1966] from Charadrius wilsonia Ord in Cuba and P. charadrii (Yamaguti, 1956) (= Proterogynotaenia charadrii Yamaguti, 1956) from C. alexandrinus L. in Japan are redescribed. Two new species are described: Paraprogynotaenia minuta n. sp. from C. alexandrinus on the Black Sea coast of Bulgaria [type-host and type-locality, based on specimens previously reported as P. charadrii], from the same host species in Tunisia and from "Tringa totanus" (the host identification is uncertain) in France [the latter two samples were previously reported as Progynotaenia odhneri Nybelin, 1916]; and Paraprogynotaenia canarisi n. sp. from C. marginatus Vieillot in the Republic of South Africa [type-host and type-locality] and from C. alexandrinus and Pluvialis dominica (Müller) in Taiwan [specimens from both localities were previously reported as Paraprogynotaenia charadrii]. P. jimenezi can be distinguished from its congeners by having 12 hooks of equal length. Among the remaining species with 18-22 hooks of varying length, P. minuta n. sp. can be distinguished by the smaller number of proglottides: up to 8 vs 15-20 for P. charadrii and P. canarisi n. sp. The latter two species can be differentiated from one another by the blade length/total length ratio of the smallest (lateral) rostellar hooks, which is less than 0.5 for P. canarisi n. sp. and 0.5 or more for P. charadrii. An identification key to the species of Paraprogynotaenia is provided and the generic diagnosis is amended. A phylogenetic analysis based on 17 morphological characters resulted in the following hypothesis for the relationships within the genus: (P. jimenezi (P. minuta (P. charadrii, P. canarisi))).     

Taxonomic revision of Driessenia (Melastomataceae)

The genus Driessenia Korth. comprises fourteen species and two varieties. Eleven species are endemic to Borneo, the remaining three species occur on Sumatra, Java or Sulawesi. Five species ( D. sessiliflora, D. planopetiolata, D. attenuata, D. grandithyrsa and D. aequiappendiculata ), one variety ( D. microthrix Stapf var. pteroclada ) and one combination ( D. dispar (Cogn.)) are new. The genus Triuranthera Back. is made a synonym of Driessenia . The revision includes a key to the species, illustrations of various floral parts and maps of distribution.     

Taxonomic revision of the subfamily Toradjiinae (Crustacea: Oniscidea: Scleropactidae)

In the present revision four genera and 32 species are recognized. One genus, Paratoradjia , and 17 species, namely Adinda malaccensis, A. sumatrana, A. palniensis, A. carli, A. nilgiriensis, A. lobata, A. triangulifera, A. rudeli, A. lamellata, Protoradjia paeninsulae, P. insularis, P. montana, P. pilosa, Paratoradjia beroni, P. vietnamensis, P. sulcata and Toradjia hirsute , are described as new. The neotype of Toradjia cephalka and lectotypes of Adinda weberi, Protoradjia jacobsoni, Toradjia gorgona and T. celebensis are established. Adinda cahgarii is considered to be a junior synonym of Adinda weberi , and A. conglobator , a species inquirenda. Toradjia dollfusi is transferred to the genus Adinda , and T. indosinensis to Paratoradjia. The characters of the group and its taxonomic position within the Oniscidea are discussed: it is transferred from the Eubelidae to the Scleropactidae, of which it constitutes a separate subfamily, the Toradjiinae. A map and comments on the distribution of genera and species are included.     

Taxonomic status of cestodes of the genus Paracaryophyllaeus Kulakowskaja, 1961 (Caryophyllidea: Caryophyllaeidae)

A taxonomic revision of cestodes of the genus Paracaryophyllaeus Kulakowskaja, 1961, parasites of cobitid fishes, has been performed. Three species (Paracaryophyllaeus gotoi (Motomura, 1927), P. kulakowskae sp. n., and P. misgurni sp. n.) are considered valid species; two are described as new species. P. dubininorum Kulakowskaja, 1961 is a young synonym of P. gotoi. The taxonomic status for P. gotoi sensu Scholz, 1989, P. gotoi sensu Scholz et al., 2001, and Paracaryophyllaeus sp. 1 and Paracaryophyllaeus sp. 2 (described in present work) needs specification.

Taxonomic revision of Rhododendron mariae (Ericaceae) and related taxa

Based on a literature survey and a field trip with specimen examination, statistical analysis including principal components analysis (PCA) on morphological characters have been carried out on Rhododendron mariae and related taxa. Cluster analysis and PCA showed three independent groups, which corresponded to three species except R. loniceriflorum . As a consequence, nine taxa are reduced to synonyms of R. mariae , and two new combinations, viz R. mariae subsp. microphyton , and R. mariae subsp. flumineum are made. Rhododendron microphyton var. trichanthum is reduced to a synonym of R. mariae subsp. microphyton , and R. malipoense to a synonym of R. mariae subsp. flumineum . Three names are synonymized and a new combination, viz R. chryocalyx subsp. meridionale , is proposed within R. chryocalyx . The third entity, R. naamkwanense , has got two new synonyms. Rhododendron loniceriflorum , with whitish pubescence on the inner corolla surface, is recognized as the fourth distinct species. Each entity is illustrated with line drawings for identification.     

A revision of the family Ciconiidae (Aves)

Behavioural and morphological characteristics of all members of the stork family are summarized. References are given to other papers where these subjects are discussed in greater detail for each group of storks. Based on the evidence now available, a revised classification is suggested (Table II) which divides the Ciconiidae into three tribes, six genera, and 17 species. The following genera (of Peters, 1931) are synonymized with other existing genera: Ibis, Sphenorhynchus, Dissoura, Euxenura , and Xenorhynchus. It is further suggested that Scopus should be placed in a suborder of its own and that Balaeniceps be placed in a monotypic family adjacent to the Ciconiidae, pending further study.     

Brachylepis gen. n.--a new genus of cestodes (Cyclophyllidea: Hymenolepididae) from shrews in Siberia and the Far East

A new genus Brachylepis gen. n. hymenolepididean cestodes associated with common shrews (Sorex) in Siberia and Russian Far East is created. These genus includes three species removed from the genus Mathevolepis: Brachylepis morosovi (Karpenko, 1994) comb. n. (type species), B. sorextscherskii (Morosov, 1957) comb. n. and B. triovaria Karpenko, 1990) comb. n. The new genus is characterized by the gradual strobila with a little number of segments, unarmed scolex with apical glandular organ, by lack of internal seminal vesicle and differential seminal receptacle, by form of uterus as horse shoe in young worms and buble-like in mature worms. A tendency of inverse proportional dependence between the number of uterus segments in the strobila and the number of hexacanths in the uterus has been noticed. The table of differential characters for the species of the genus Brachylepis is proposed.     

Ultrastructure of the reticulate uterus and specific features of matrotrophy in three species of higher cestodes (Cestoda,Cyclophyllidea)

The ultrastructure of the reticular uterus has been analyzed in pregravid and gravid proglottids of cyclophillid cestodes dwelling in water (Alcataenia dominicana and A. larina) and in terrestrial hosts (Arostrilepis tenuicirrosa). Cells of the medullary parenchyma surrounding the uterus are filled with lipid inclusions in all species investigated. The hypertrophic development of small excretory ducts that surround the uterus, contact the uterine epithelium, and penetrate the diverticula is characteristic of Alcataenia dominicana and Arostrilepis tenuicirrosa. A comparative analysis of the results and the data available for other cestode species allow for the assumption that the reticulate structure of the uterus, lipid accumulation, and contacts between the uterine epithelium and the excretory ducts are morphological and functional adaptations that enable matrotrophy and the attainment of maximal fecundity by cyclophillid cestodes.
